Embodiment 1

[0037] Such as figure 1 As shown, an in-situ biological nest micro-nano aeration water purification system in this embodiment includes a floating box, and the inside of the box is divided into a water distribution area 13, an air bubble generation area 14, a packing area and a water distribution area from bottom to top. Amplification area 16, filler area filler A area 15 and filler B area 9, the water distribution area 13 and the bubble generation area 14 are separated by a fixed split layer stainless steel plate 5, the bubble generation area 14 and the filler area filler A Between the regions 15, between the filler A region 15 and the filler B region 9 in the packing region, and between the filler B region 9 and the amplification region 16 are separated by a stainless steel perforated plate 6 with a movable separation layer.

[0038] The submersible pump 1 is vertically arranged, and the submersible pump 1 is fixed in the water distribution area 13 and distributed on the cent...

Embodiment 2

[0047] An in-situ bio-nest micro-nano aeration water purification system of Example 1 was used for experiments in a landscape lake south of Cuiping Bridge in Wuxi City, Jiangsu Province. The length of the lake is 226m, the width of the lake is 12.8m, the number of installed equipment is 1, the diameter of the equipment is 600mm, and the height of the equipment is 1380mm. 200mm, 250mm, 150mm and 150mm. Put 8.28kg of self-made ceramsite in area A of equipment packing 1 # , the diameter of ceramsite is 4±2mm; put 8.28kg homemade ceramsite 2#, the diameter of ceramsite is 8±2mm. Put 5.44kg of spherical microbial expansion curing agent in area B of the equipment packing. The diameter of the microbial expansion curing agent is 4±2mm. The composition of the microbial expansion curing agent is shown in Table 1. Power consumption of the equipment: 220V alternating current, the distribution box is used to connect to the nearby power supply; the weight of the equipment: 90Kg (with its ...

Abstract

The invention relates to a system and a method for in-situ biological nest micro-nano-aeration water purification. The interior of a box body is divided into a water distribution area, a bubble generation area, a filler area and an amplification area from bottom to top, a plurality of holes are formed in the side wall of the water distribution area to introduce sewage and air, and a submersible pump is arranged in the water distribution area; a micro-nano-bubble generating device is of a symmetrical structure formed by combining two hemispherical containers and a cylindrical container, two ends of each hemispherical container are each provided with a circular hole used for spraying out micro-nano-bubbles, the cylindrical container is provided with a water inlet pipe connected with the submersible pump, two hollow C-shaped pipes which are sequentially arranged are arranged on the inner surface of the cylindrical container to divide the connecting part of a water inlet pipe or a water outlet pipe of a previous C-shaped pipe and the cylindrical container into two parts, and the cross section area of each part is smaller than that of an outlet part of the water inlet pipe or the C-shaped pipe; the filler area comprises at least two layers of filler areas; a plurality of water outlets are formed in the side wall of the amplification area; and the system further comprises a power device.

Description

technical field [0001] The invention relates to an in-situ biological nest micro-nano aeration water purification system and method, which are used for in-situ disposal of natural water bodies such as rivers and lakes, and belong to the field of environmental engineering. Background technique [0002] With the rapid economic development and the acceleration of urbanization, the pollution load of rivers, lakes, landscape water bodies, etc. is increasing day by day, leading to the increasingly serious problems of water body pollution and eutrophication. Excessive discharge of nutrients such as nitrogen and phosphorus into the natural water body leads to eutrophication of the water body, which reduces the transparency of the water body and makes it difficult for sunlight to penetrate the water layer, thus affecting the photosynthesis of plants in the water body and the release of oxygen. The massive reproduction of plants consumes a lot of oxygen in the water, causing a serious...
